First details of the third generation mid-range Moto G series and entry-level Moto E (2016) have surfaced online ahead of launch.

Popular tipster Roland Quandt has posted key features and price details of the 2016-based Moto G series and Moto E (3rd gen) smartphones on Twitter. He claims that the mid-range phone will come in two variants -- Moto G Plus and Moto G (4th gen).

As the name implies, the former model is said to be the top-end one among the two. It is expected to feature 5.5-inch display, 16GB storage, a 16MP camera on the back and cost €280(around $316/Rs.21,064).

On the other hand, generic Moto G (4th gen) model is also said to sport 5.5-inch screen and 16GB inbuilt memory, but comes with less-superior 13MP snapper on the rear. It is expected to set you back by €240(around $271/Rs.18,045) . Both the Moto G series handsets will be available in white and black colour options.

Budget mobile phone series Moto E (2016) is expected to come with major upgrade over its 4.5-inch Moto E (2nd Gen.) in terms of design and as well as internal hardware. This time, the company has reportedly decided to bump up the screen size to 5.0-inch and incorporate HD (1280x720p) resolution display, 2GB RAM and 16GB inbuilt storage.

In a related development, world renowned Twitter spy Evan Blass (aka @evleaks) has posted an image featuring the lower-half of Moto G4 Plus with physical home button. It is believed that the device's home button will double-up as the fingerprint-based screen unlock system.

Though there is no proof to validate the aforementioned reports, specifications details of the devices are more likely to turn true as most of the Lenovo's Moto series rivals, which are already available in the market boast similar features.

For the uninitiated, the upcoming Moto G and Moto E series will be the first Motorola-less branded phones. Instead, they will come with "Moto by Lenovo" tag.
